NIGP 21010: Blocks, Hollow and Solid, Lightweight

NIGP 21010 Blocks, Hollow And Solid, Lightweight is an Item code under which state and local governments procure concrete masonry units and related products for infrastructure repair, utility work, and construction projects. Recent solicitations show demand for concrete half-blocks (standard 8-inch units with double corners and single core), modular retaining wall units, and precast concrete components for sewer and water infrastructure. The Florida Department of Agriculture and Consumer Services issued an ITB for approximately 600,000 concrete half-blocks across three coastal counties (Brevard, Dixie, and Charlotte); Leon County, Florida bid concrete half-blocks; and Santa Clara County's Sanitation District No. 2-3 specified precast concrete sanitary sewer manholes as part of a larger sewer rehabilitation project. Issuing bodies span state agencies, counties, and municipal public works and housing authorities, with Arizona cities (Peoria and Phoenix) and California jurisdictions (Santa Clara County, Palm Desert Housing Authority) representing significant recent activity.
